Q: Tim Tebow is probably unmatched as a weightlifter among NFL quarterbacks. But could Tebow’s daily devotion to weightlifting adversely affect his accuracy as a passer?

A: The NFL lockout, which started March 12, has limited most players’ offseason workouts to conditioning that includes flexibility training and weightlifting.

Tebow came into the NFL bigger in the upper body than most quarterbacks because of his role as a running QB in Florida’s spread-option offense. That role obviously required extensive weightlifting.

NFL teams want their quarterbacks strong enough to withstand the punishment that comes with playing the most important position on the field. But they also want their quarterbacks to have a smooth throwing motion that comes from shoulder flexibility.

Quarterbacks at the NFL scouting combine aren’t asked to do the bench press because teams don’t see that as a proper testing tool for evaluation of players at that position. But some quarterbacks do the bench press to show they are eager to compete.

Vanderbilt’s Jay Cutler did the bench press at the scouting combine in 2006. He did 23 repetitions of 225 pounds, a performance that was better than some linebackers at that combine. Cutler, a first-round draft pick of the Broncos who’s now with the Bears, and Alabama State’s Tarvaris Jackson (now with the Vikings) were the only quarterbacks who did the bench press that year. Jackson did 22 repetitions. No quarterbacks did the bench press at this year’s scouting combine.

Tebow’s throwing motion is more extended than most quarterbacks. But his biggest issues are improving his anticipation and his footwork in the pocket. It’s all a matter of timing. Broncos coach John Fox and executive John Elway want Tebow to throw the ball quicker. And part of that is having enough flexibility in the throwing shoulder to consistently deliver the ball to the right spot.
